CURRENT REPORT ON FORM 8-K

ITEM 1.01 | Entry Into a Material Definitive Agreement

On July 23, 2024, ACNB Corporation (“ACNB”) and, its wholly-owned subsidiaries, ACNB Bank and ACNB South Acquisition Subsidiary, LLC (“Acquisition Subsidiary”) and Traditions Bancorp, Inc. (“Traditions”) and Traditions Bank entered into an Agreement and Plan of Reorganization (the “Agreement”) which provides that, subject to the terms and conditions set forth in the Agreement, Traditions will merge with and into Acquisition Subsidiary with Acquisition Subsidiary surviving the merger. In addition, as soon as practicable after the merger of Traditions with and into Acquisition Subsidiary, Traditions Bank will merge with and into ACNB Bank.

Subject to the terms and conditions of the Agreement, each share of Traditions common stock will be converted into the right to receive 0.7300 share of ACNB common stock. Traditions shareholders will receive cash in lieu of fractional shares.

Subject to the terms and conditions of the Agreement, (i) each Traditions restricted stock unit issued that is outstanding immediately before the effective time of the merger shall vest in full and be converted automatically into the right to receive the merger consideration, and (ii) each outstanding option to purchase shares of Traditions common stock that is outstanding and unexercised at the effective time of the merger, shall be redeemed for cash.

The Agreement contains customary representations and warranties from the parties, and the parties have agreed to customary covenants and agreements, including, among others, covenants and agreements relating to (1) conduct of their respective businesses during the interim period between execution of the Agreement and the closing of the merger, (2) Traditions’ obligation to facilitate its shareholders’ consideration of, and voting upon, the necessary approval and adoption of the Agreement, (3) ACNB’s obligation to facilitate its shareholders’ consideration of, and voting upon, the issuance of the common stock to Traditions shareholders, (4) the recommendation of the board of directors of Traditions in favor of the necessary approval by its shareholders, (5) Traditions’ non-solicitation and other obligations relating to alternative business combinations, and (6) the addition of three (3) members of Traditions’ current board members, one of which shall be Eugene J. Draganosky, to the boards of directors of ACNB and ACNB Bank. Further, as of the effective time of the merger, Mr. Draganosky will be appointed as an additional Vice Chair of the boards of directors of ACNB and ACNB Bank. In connection with the Agreement, ACNB and ACNB Bank have entered into an employment agreement with Thomas J. Sposito. The employment agreement becomes effective contingent upon the completion of the merger.

The boards of directors of ACNB and Traditions have unanimously approved the Agreement. The Agreement and the transactions contemplated by it are subject to the approval of Traditions’ shareholders, ACNB’s shareholders for the share issuance, regulatory approvals, and other customary closing conditions. The transaction is intended to qualify as a tax-free reorganization for federal income tax purposes.

The Agreement provides certain termination rights for both ACNB and Traditions. Upon termination of the Agreement under certain circumstances, Traditions will be obligated to pay ACNB a termination fee of $3.0 million.

The foregoing description of the Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement, which is attached hereto as Exhibit 2.1 and is incorporated herein by reference. The representations, warranties and covenants of each party set forth in the Agreement have been made only for purposes of, and were and are solely for the benefit of the parties to, the Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Accordingly, the representations and warranties may not describe the actual state of affairs at the date they were made or at any other time, and investors should not rely on them as statements of fact. In addition, such representations and warranties (1) will not survive consummation of the merger, unless otherwise specified therein, and (2) were made only as of the date of the Agreement or such other date as is specified in the Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Agreement, which subsequent information may or may not be fully reflected in the parties’ public disclosures. Accordingly, the Agreement is included with this filing only to provide investors with information regarding the terms of the Agreement, and not to provide investors with any other factual information regarding ACNB or Traditions, their respective affiliates or their respective businesses. The Agreement should not be read alone, but should instead be read in conjunction with the other information regarding ACNB, Traditions, their respective affiliates or their respective businesses, the Agreement and the merger that will be contained in, or incorporated by reference into, the registration statement on Form S-4 that will include a joint proxy statement of Traditions and ACNB and a prospectus of ACNB, as well as in the Forms 10-K, Forms 10-Q, Forms 8-K and other filings that ACNB makes with the Securities and Exchange Commission (“SEC”).
